[mapserver-users] Dynamic Watermark

[Olivier Gagnon]

Hi there,


I'm new to mapserver.


I need to develop a custom function to add a dynamic watermark using a wms layer.


The process is simple : I have a polygon layer with a "providerName" field. This layer will be used as an overlay on top of other layers.


I need to get the features returned byt the spatial query, get all the provider names for the current bbox by using the features collection, add a point to the layer (ex: bottom center) with the names of the providers as a label. This has to be done on each pan and zoom.


I think it's quite simple so how would I get the list of features returned by the spatial query ? How do I add the point and the label ?


I'm thinking to use python. Where do I put the code ? How do I link it to the mapfile ?


I'll continue reading in the meantime.


Thanks
